I think some of the above noted tasks are a tall order for any knife. In all seriousness, get a Mora and a P38 can opener and you will be good to go. Granted they aren't "cool" looking but especially with this being your first knife, you can't go wrong. They are inexpensive and easy to sharpen and will serve you well in all of your outdoors activities. Just grab the nearest rock if you need to hammer something.
